I have a SAPPHIRE 7970 Boost. If I had the 7970 GHz Vapor-x, I am confident I could have gotten at least a 35-40% performance increase over a stock 7970/680. Besides doing this for fun though, I also did it to compare to the Geoforce Titan benchmarks that are gonna come out soon. I'm gonna see how well a 7970 +30% does against it. If it comes anywhere near close to it, then that means a $400 card is near a $1000 card, and a 7970 GHz Toxic could probably trade blows with it if overclocked a ton.

So anyone else get similar results to me?

How strong do you guys think a Titan will be compared to a 7970 Toxic?

From the reports Tom's has posted, it looks like the Titan will out-perform the 7970, pretty much across the board (even the Toxic version).

Still (as you know) the HD7970 is a VERY strong GPU. The next generation of Radeon offering looks to be very promising as well.

Idk I read that review too, and the 7970GHz fell within 20-30% many times. I feel it would be very doable.

Problem is, all of the benchmarks TH ran are with programs I really can't reproduce. However I may check out other websites...

Keep in mind that OCing the Titan would likely widen the gap. On paper, the Titan is pretty darn impressive and it should be given the cost.

I know the Titan can overclock, but a $380 card should NEVER EVER reach a $1000 card. That would be like a 7750 beating a 7870. Just NO!


Also I agree the Titan is impressive ON PAPER. However I really expected a larger jump in performance from those kinds of stats...

Time and driver maturity will tell on Titan's true performance potential, my friend, and lower the costs.

Don't get me wrong, I am a huge fan of the HD7970, especially in terms of performance for the $$$.

I am about to buy one myself to replace my HD6970 (which has been a workhorse).
